Just my 2 cents:

I am CO plat who flies exclusively domestically. I am very satified with the domestic upgrades (as i'm sure most of you are), and have mostly very positive interactions with all CO employees.

With that being said, I feel I come down on venk/NJDavid/vulcan/etc.'s side as to CO's HoKeY lottery and BF upgrade policy. I know if I did any international travel, I would be going NW too.
